Drawing attention as one of main components of EVs as well as small batteries for IT devices and also aiming at the ESS market as well

As there is a growing need for high energy density batteries used as power supplies with the development of technologies for mobile devices and increase in the demand, and there has been considerable progress in research on electric vehicles to replace existing fossil fuel powered cars, active research on lithium secondary batteries as power sources is in progress.

Among components of lithium secondary batteries, cathode materials are one of very important factors determining battery capacity and performance. Although lithium cobalt oxide (LCO) is mainly used, but there are disadvantages that it is structurally instable, expensive due to limited reserves of cobalt as a raw material, and insufficient to be used as a power source of electric vehicles.

For this reason, a lot of attention is paid on the development of cathode materials to replace LCO; especially lithium nickel cobalt manganese oxide (NCM) has rapidly replaced LCO due to a lot of advantages in terms of stability, lifetime, and price. NCM cathode materials are one of READ MORE >
